Two issues here.

What type of shoulder belts work best with a HANS®? As the inventors, developers and only marketers of HANS® devices worldwide, we recommend any 3" belts for use with HANS® devices. Based upon better stretch and aging characteristics, we prefer that drivers use polyester belts. However, both nylon and polyester work fine with HANS® devices.

My belts sometimes slip off the device. What's wrong? Properly mounted belts do not slip off the device. If your shoulder belts will not stay securely over the device when you are firmly belted in chances are that you do not have the shoulder belt mounts properly located in your chassis. Please review the section of the owner's manual concerning shoulder belt mounting.

The tricky point about HANS fitting for some might seem to be that it should not touch the seat. Another issue might be the distance between the seat belt shoulder harness mounting points and the driver which should be "close". Good advice anyway.
